Why Beef Does Not Have a Carbon Footprint

Nearly people have heard it by now: Our meat habit is bad for the earth. Polling suggests that tens of millions of people are taking this message seriously: One in four Americans said they tried to cut back on meat in the last year, and one-half of those cited environmental concerns as a major reason. The pop food site Epicurious recently announced they've stopped publishing recipes with beef in them, because of beef's climate impacts, setting off the latest round of discussion on meat's effects on the environment.

Cutting meat consumption is equally smart an idea as advertised. Industrial farming — the source of 99 percent of the meat Americans eat — provides the globe with cheap meat, just it does and then at a terrible environmental and moral cost.

Where it gets complicated is when people decide which meat, exactly, they'll exist cutting back on. Often, it'southward beef that loses out in that calculus. And often, the messaging is that nosotros can save the earth past switching out our beef consumption for chicken.

The problem with this message is that switching beefiness for chicken basically amounts to trading one moral catastrophe for some other.

The environmental reasons for cutting beef from ane'south nutrition are clear. Most of the climate bear upon of animal agriculture comes from raising cows for beefiness. Cows produce methane, a greenhouse gas that is a major contributor to global warming; information technology'southward much more potent than carbon dioxide. Transitioning abroad from eating beef to eating other mill-farmed animal products undoubtedly reduces the carbon impact of a person'south diet.

Just the transition away from beefiness can stop upwardly being a Pyrrhic victory if it drives up the world's rapidly rising chicken consumption. That ends upwards swapping one disaster — the climate crunch and beef farming'due south office in information technology — for another: the moral disaster of industrial chicken production.

To put it simply, it takes many, many more chicken lives than cow lives to feed people. Cows are big, then raising i produces about 500 pounds of beef — and at the rate at which the average American eats beef, information technology takes about viii.5 years for 1 person to consume one cow. Merely chickens are much smaller, producing only a few pounds of meat per bird, with the average American eating near one whole chicken every two weeks. To put it another manner, each year we eat about 23 chickens and just over one-tenth of 1 cow (and about a third of i pig).

Considering chickens are so much smaller than pigs and cows, more than chickens endure for the nutrient we eat.

The choice to swap beef for chicken is further compounded by the differences in their quality of life. Cows are raised for slaughter on pastures and feedlots — enclosed spaces where they're fed grain in preparation for slaughter. Nigh animate being well-being experts say that the life of a cow raised for beef is punctuated by traumatic events and cut needlessly curt, only information technology's non ceaseless torture.

On the other hand, factory-farmed chickens — and that'south 99 per centum of all chickens we eat — accept an awful life from the moment they're built-in to the moment they're slaughtered. The most efficient mode to raise chickens is in massive, ammonia-high-strung, noisy warehouses, where the birds grow so rapidly (due to genetic selection for excessive size) that their legs can't back up their weight. They alive about six weeks and so are killed.

Then switching from cows to chickens is a style to somewhat reduce carbon emissions — but it comes with a massive increase in animal suffering.

Choosing between the ii is a knotty dilemma that tends not to be discussed often. But this tension isn't inevitable. Later on all, climate advocates and fauna advocates are on the aforementioned side: supporting a transition away from industrial agronomics. And well-nigh people care about both animals and the environment, then addressing factory farming is a uncomplicated win-win.

The solution to manufacturing plant farming's many harms tin can't be shuffling consumers betwixt craven and beef depending which of their devastating impacts is on the top of our minds. And consumers shouldn't accept equally inevitable the pick between torturing animals and dramatically worsening global warming. There is a path to a food system that doesn't strength united states of america to choose, but nosotros're going to need to take much bigger steps, in terms of policy and consumer choice, to get there.

The climate impacts of animate being agriculture

At that place's no way effectually it: Raising beefiness actually is bad for the world.

About 15 percentage of all global greenhouse gas emissions come from livestock. Beef is the biggest culprit, accounting for most 65 per centum of all greenhouse gas emissions from livestock. Cattle produce marsh gas, and they likewise require lots of carbon-intensive land conversion and carbon-intensive feed. Co-ordinate to the World Resources Institute, an environmental research nonprofit, beef requires xx times more land and emits 20 times more than greenhouse gas emissions per gram of edible poly peptide than common plant proteins, like beans.

Beefiness's defenders have argued that it doesn't have to be that style. Proposals from feeding cattle seaweed in order to reduce their methane emissions to "regenerative farming" that tin can better soil and country have been aired, and some have been implemented on a small scale.

But American consumers shouldn't kid themselves: If you purchase beefiness from a grocery store shelf or in a restaurant in America, unless you get very far out of your way to trace, source, and verify the sustainable history of that meat, yous're getting the production of a carbon-intensive industrial procedure.

Epicurious nodded to this reality in its declaration that it would stop publishing beef recipes: "We know that some people might presume that this decision signals some sort of vendetta against cows — or the people who eat them. Only this decision was not made because we hate hamburgers (we don't!). Instead, our shift is solely about sustainability, about non giving airtime to i of the world's worst climate offenders. We recall of this decision as not anti-beef but rather pro-planet."

A May xx commodity in the New York Times about the rise of "climatarians" underscored the emerging primacy of climate in people's dietary choices, noting that climate-conscious eaters have moved in a meatless direction, simply that many still believe that "chicken or lamb are much meliorate choices than beef."

It's entirely understandable that some consumers have decided it's time to move away from beefiness. And aye, individual consumer decisions do matter: Researchers have studied what'southward called the elasticity of supply for meat — that is, how much consumer demand affects production — and determined that when consumers demand fewer hamburgers, fewer cows are raised.

Simply whether that'due south, on the whole, a practiced matter depends a lot on what you choose instead.

The fauna-cruelty bending

It's no fun to exist a cow on a factory farm. But animal welfare experts concur: Being a chicken is much worse.

That's because of the commercial incentives behind both cow and chicken production. Ranchers have establish it most efficient to enhance cows outdoors on pasture and then fatten them for slaughter on feedlots. There'south a lot wrong with how nosotros heighten them — cows are painfully dehorned, mass distribution of antibiotics keeps them healthy at the expense of breeding antibiotic resistance, and while there'southward a federal law that requires pigs and cattle to be rendered unconscious prior to slaughter, information technology's non ever followed and only minimally enforced.

But chickens have it much worse. The cheapest mode to enhance chickens is in massive, crowded indoor warehouses where they never see the sun. Over time, companies have bred chickens to grow so fast their joints fail as they reach full size. Observational studies suggest they spend much of their time sitting still, in also much hurting to movement.

"In virtually cases, they suffer far more than than beef cattle, who accept more than legal protections, suffer fewer health problems, and are generally less intensively confined," Leah Garces, the president of Mercy for Animals, has argued.

And while a cow suffers and is slaughtered to produce around 500 pounds of meat, a craven produces virtually 4 to 5 pounds of meat. Then a switch from beef to chicken is actually a switch from a tough life for i cow to an awful life for effectually 100 chickens.

That's why many advocates calling for an finish to industrial farming have mixed feelings about the move confronting beefiness. Is it right to effort to salvage some carbon emissions by causing even more than animate being suffering?

And chicken is no panacea for the climate either. "Its impact on the climate just looks benign when compared with beef's," Garces points out. "Greenhouse gas emissions per serving of poultry are 11 times higher than those for 1 serving of beans, so swapping beef with chicken is alike to swapping a Hummer with a Ford F-150, not a Prius."

Another ofttimes proposed option is switching to fish. But aquaculture, too, causes intense beast suffering and massive ecological consequences. There simply aren't humane, sustainable, widely bachelor, and inexpensive meats.

Giving consumers better choices

Consumers who are reconsidering their meat consumption — for the sake of animals, the planet, or both — are doing a courageous thing, and the bespeak of observing the added complications of this selection isn't to discourage them. Fixing our broken food organization is going to require substantial policy and corporate changes, as well equally consumers making better choices. The beef versus chicken conversation is part of how nosotros get there.

Only what the dilemma lays bare is that at that place's no meat consumption that will save the world. Meat is one of the most pop foods, and notwithstanding building a ameliorate world is going to require inducing consumers to switch away from it — and non just switch between different categories of meat every bit they weigh the different environmental and moral catastrophes it causes.

That's why some animal advocates in the last few years have switched from convincing consumers to go vegan — which can be too big of a spring for many — to advocating for plant-based meat products. These constitute-based products are already hard to distinguish from the originals, while having a lighter carbon footprint and no impact on animals. If y'all avert beef past switching to plant-based meat products, you actually are improving the world and improving conditions for the humans and animals that live on it.

Only despite all these complications, when prominent food sites take beef out of their lineup or when Americans tell pollsters they're trying to cut back on beef, it'south cause for optimism — fifty-fifty though in the brusk term, depending what they replace it with, it could make things worse. Our food system delivers meat cheaply at an awful price. Starting more conversations nearly that price and how we can mitigate it is a good affair, fifty-fifty if it'due south a conversation a long way from a satisfying resolution.

Correction, May 24: A previous version of this article misstated a resource-per-calorie comparison of meat and vegetables. It has been updated to land that "beef requires 20 times more land — and emits 20 times more than greenhouse gas emissions — per gram of edible protein than mutual plant proteins."
